FAQs

Who is LONDEVITY® for?

Anyone who wants a daily habit that is good and genuinely enjoyable: busy people who don't stick with capsules, people who train, and anyone looking for a thoughtful gift. Enjoy it as part of a varied, balanced diet and a healthy lifestyle.

How much should I have?

Bars: one bar a day, maximum. Gift boxes: four pieces a day. Coffee: one cup (12 g) a day. Exact amounts are on each pack.

Is it a supplement or medicine?

No. It is a food: dark chocolate (or coffee) with functional food ingredients. It is not intended to diagnose, treat, cure or prevent any disease. If you are pregnant, breastfeeding, taking medication or have a medical condition, speak to your GP or pharmacist first.

Is it vegan? What about allergens?

All our bars and our coffee are 100% vegan; our gift boxes are not. Muscle Up, Recovery & Sleep, Longevity Mix and Matcha contain peanuts; Matcha also contains cashews and almonds. Energy Bar and Absolute Dark have no nuts in the recipe, but all our products are made in a kitchen that also handles peanuts, nuts and sesame. Our bars contain no wheat and are gluten free.

How much sugar is in it?

Our bars have no added sugar. Most contain under 0.5 g sugar per 100 g; Matcha has about 1.3 g per 100 g from its dried fruit. The exact figure is on every label. The coffee has no added sugar. The 85% gift box contains some sugar from the chocolate: see its label.

Does it make a good gift?

Yes. The Christmas Gift Set comes gift-wrapped with a handwritten card, and you can add a gift message to any order in the gift message box in your basket. Order by 16 December for UK Christmas delivery. See the Christmas Gift Guide.

Where is it made and where does the cacao come from?

Handcrafted in small batches in London, with single-origin cacao from Ghana.
